In ‘Moral Enhancement, Freedom, and the God Machine’, Savulescu and Persson argue that recent scientific findings suggest that there is a realistic prospect of achieving ‘moral enhancement’ and respond to Harris's criticism that this would threaten individual freedom and autonomy. I argue that although some pharmaceutical and neuro‐scientific interventions may influence behaviour and emotions in ways that we may be inclined to evaluate positively, describing this as ‘moral enhancement’ presupposes a particular, contested account, of what it is to act morally (...) and implies that entirely familiar drugs such as alcohol, ecstasy, and marijuana are also capable of making people ‘more moral’. Moreover, while Savulescu and Persson establish the theoretical possibility of using drugs to promote autonomy, the real threat posed to freedom by ‘moral bioenhancement’ is that the ‘enhancers’ will be wielding power over the ‘enhanced’. Drawing on Pettit's notion of ‘freedom as non‐domination’, I argue that individuals may be rendered unfree even by a hypothetical technology such as Savulescu and Persson's ‘God machine’, which would only intervene if they chose to act immorally. While it is impossible to rule out the theoretical possibility that moral enhancement might be all‐things‐considered justified even where it did threaten freedom and autonomy, I argue that any technology for biomedical shaping of behaviour and dispositions is much more likely to be used for ill rather than good.

We respond to a number of objections raised by John Harris in this journal to our argument that we should pursue genetic and other biological means of morally enhancing human beings (moral bioenhancement). We claim that human beings now have at their disposal means of wiping out life on Earth and that traditional methods of moral education are probably insufficient to achieve the moral enhancement required to ensure that this will not happen. Hence, we argue, moral bioenhancement should be sought (...) and applied. We argue that cognitive enhancement and technological progress raise acute problems because it is easier to harm than to benefit. We address objections to this argument. We also respond to objections that moral bioenhancement: (1) interferes with freedom; (2) cannot be made to target immoral dispositions precisely; (3) is redundant, since cognitive enhancement by itself suffices.

abstract As history shows, some human beings are capable of acting very immorally. 1 Technological advance and consequent exponential growth in cognitive power means that even rare evil individuals can act with catastrophic effect. The advance of science makes biological, nuclear and other weapons of mass destruction easier and easier to fabricate and, thus, increases the probability that they will come into the hands of small terrorist groups and deranged individuals. Cognitive enhancement by means of drugs, implants and biological (including (...) genetic) interventions could thus accelerate the advance of science, or its application, and so increase the risk of the development or misuse of weapons of mass destruction. We argue that this is a reason which speaks against the desirability of cognitive enhancement, and the consequent speedier growth of knowledge, if it is not accompanied by an extensive moral enhancement of humankind. We review the possibilities for moral enhancement by biomedical and genetic means and conclude that, though it should be possible in principle, it is in practice probably distant. There is thus a reason not to support cognitive enhancement in the foreseeable future. However, we grant that there are also reasons in its favour, but we do not attempt to settle the balance between these reasons for and against. Rather, we conclude that if research into cognitive enhancement continues, as it is likely to, it must be accompanied by research into moral enhancement. (shrink)

In his challenging paper,1 Vojin Rakic argues against our claim that ‘there are strong reasons to believe’ that moral bioenhancement should be obligatory or compulsory if it can be made safe and effective.2 Rakic starts by criticising an argument that we employed against John Harris.3 ,4 In this argument we maintain, among other things, that moral bioenhancement cannot be wholly effective if our will is free in what is called an ‘indeterministic’ or ‘contra-causal sense’; that is, if our choices are (...) not fully determined by our biology and environmental circumstances. Rakic contends that we ‘do not take into account the possibility that we can have an entirely free will that does not limit the effectiveness of moral bio-enhancement’. We can use ‘our freedom to decide to be morally bio-enhanced’.In reply, we would like to insist that if our freedom is freedom in this indeterministic sense, we cannot use this freedom to decide to subject ourselves to effective moral bioenhancement, since this effectiveness presupposes that our will is fully determined by biological causes that this enhancement influences. If certain sub-atomic processes are indeterministic, probabilistic, we cannot make them deterministic. We cannot change the laws …. (shrink)

Elizabeth Fenton has criticised an earlier article by the authors in which the claim was made that, by providing humankind with means of causing its destruction, the advance of science and technology has put it in a perilous condition that might take the development of genetic or biomedical techniques of moral enhancement to get out of. The development of these techniques would, however, require further scientific advances, thus forcing humanity deeper into the danger zone created by modern science. Fenton argues (...) that the benefits of scientific advances are undervalued. The authors believe that the argument rather relies upon attaching a special weight to even very slight risks of major catastrophes, and attempt to vindicate this weighting. (shrink)
